A deleted scene from HBO's House of the Dragon would have seen the prequel drama adding to the lore of Game of Thrones with a never-before-rendered moment.

EW can provide an exclusive sneak peek at House of the Dragon: Inside the Creation of a Targaryen Dynasty, the officially licensed making-of book written by author Gina McIntyre for publisher Insight Editions. Two pages showcase images from a scene that was filmed for the series but later scrapped: the top-secret Kingsguard induction ceremony.
